Strongsville, Ohio, USA, May 1, 2019 – Rafter Equipment Corporation has shipped four (4) RT-1500 laser weld squeeze boxes to a major North American automotive parts supplier. The boxes incorporate a 14-roll design that securely holds the HSLA profile shape for optimum laser welding. The boxes are to be installed on a pair of Rafter RF-1500S-28 rollforming mills supplied to the same customer some years ago.
Strongsville, Ohio, USA, March 30, 2018 – Rafter Equipment Corporation has shipped an RT-3000 Single-Tool HFI Weld Bead Upset Trimmer with Bead Winder to a North American custom roll form parts producer. The equipment includes a cam actuated quick-lift feature to raise and lower the trimming tool automatically when the mill stops or manually when a coil end joint passes underneath. The use of a cam motion locks the tool in the down position mechanically. It also returns the tool to the preset trimming position automatically after it has been raised. The lower support roll tool was contoured to match the direct-welded profile section.
The Bead Winder is mounted to the top surface of the trimmer. It includes a variable speed motor with a slip clutch mechanism for optimum tension control. This feature greatly reduces bead breakage during winding. A pneumatic push-off mechanism breaks the cooled bundle free of the winder tines for easy disposal.

Strongsville, Ohio, USA, August 18, 2013 – Rafter Equipment Corporation will introduce a new roll forming machine at the upcoming FABTECH Show in Chicago in November. Originally founded as a roll forming machine builder, the company is now known more for its tube mill machines. Although the current machine designs are used in roll forming applications, they are typically more than what is needed (i.e., overkill) for the roll forming industry.
In order to better meet the needs of today’s roll former, a new machine design specific to the industry was necessary. The challenge for the company was to create a less costly design with modern quick-change capabilities while still maintaining high-quality construction and robust strength. The company will showcase a 2-pass roll stand assembly at the show. The stand will highlight a lower cost “rafted” machine design and an easily customized drive train arrangement.
